Abstract (en)

[origin: WO2019219558A1] The invention relates to a system (10) for an electrically driven vehicle (60), the system (10) comprising at least one motor controller (14) for controlling at least one electric motor (18), by means of which at least one driven wheel (64) of the vehicle (60) can be driven. The system (10) further comprises at least one brake controller (12) for controlling friction brakes (58), by means of which each of a plurality of driven wheels (64) and/or non-driven wheels (66) can be braked. The brake controller (12) and the electric motor controller (14) each have a data interface (16a, 16b, 16c), which is a bus interface (17), in particular a CAN bus interface (19). The brake controller (12) and the electric motor controller (14) are configured to transmit and/or to receive data via the first data interfaces (16a, 16b, 16c) at a predefined maximum data transfer rate (23). The brake controller (12) and the electric motor controller (14) each further have a second data interface (38a, 38b, 38c), the second data interface (38a, 38b, 38c) being designed to transmit and/or to receive data at a higher data transfer rate (35) than the maximum data transfer rate (23) of the first data interface (16a, 16b, 16c). The brake controller (12) and the electric motor controller (14) are further configured to exchange data, in particular through the transmission and/or receiving of data, via the second data interfaces (38a, 38b, 38c) at a higher data transfer rate (35) than via the first data interfaces (16a, 16b, 16c). The invention further relates to a vehicle (60) having a system (10) and to a method for operating a vehicle (60) or a system (10).
